AD9788BSVZRL

Digital To Analog Converters Overview

The AD9788BSVZRL is a dual-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., operating at a maximum sample rate of 800 MSPS. It features a low-power 32-bit complex numerically controlled oscillator (NCO) for carrier placement within the DAC bandwidth, adding less than 300 mW to power consumption. The device includes auxiliary DACs for I and Q gain matching and offset control, along with programmable phase compensation. It utilizes an internal reference voltage of 1.2 V and operates on 3.3 V analog/digital supplies and 1.8 V clock/digital supplies. The component is housed in a 100-lead TQFP package with an exposed pad.

Digital To Analog Converters Feature Summary

• Dual 16-bit DAC architecture with 800 MSPS sampling rate
• Integrated low-power 32-bit complex NCO (<300 mW)
• Auxiliary DACs for I/Q gain and offset adjustment
• Internal 1.2 V voltage reference

Digital To Analog Converters Applications

• Wireless infrastructure base stations
• Digital high or low IF synthesis
• Transmit diversity systems
• Wideband communications including W-CDMA and WiMAX

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BSVZRL' against the manufacturer's current ordering guide to confirm packaging type and reel specifications. Ensure compatibility with the 100-lead TQFP footprint and thermal requirements for the exposed pad connection during assembly.

Digital To Analog Converters Selection Notes

Select this component when 16-bit resolution and 800 MSPS throughput are required for direct conversion or high-IF transmit applications. Consider the integrated NCO and auxiliary DACs if system-level gain, offset, and phase calibration are needed without external components.

Digital To Analog Converters Part Context

The AD9788 is part of the TxDAC+ family, specifically designed for high dynamic range applications. It shares the same pinout and form factor as the AD9785 (12-bit) and AD9787 (14-bit), allowing for resolution flexibility within the same hardware design while offering superior linearity and spurious-free dynamic range due to its 16-bit architecture.

Digital To Analog Converters Replacement Considerations

The AD9787BSVZRL and AD9785BSVZRL are pin-compatible alternatives within the same datasheet, offering 14-bit and 12-bit resolutions respectively. Verify that the reduced resolution meets the system's dynamic range requirements before substituting.
